mybatis的分页插件pagehelper5.x.x使用

首先pom加入pagehelper的依赖

    com.github.pagehelper
    pagehelper
    5.1.2

spring集成pagehelper

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="mapperLocations">
        <array>
            <value>classpath:mapper/*.xmlvalue>
        array>
    property>
    <property name="typeAliasesPackage" value="com.isea533.mybatis.model"/>
    <property name="plugins">
        <array>
            <bean class="com.github.pagehelper.PageInterceptor">
                
                <property name="properties">
                    <value>
                        helperDialect=mysql
                        reasonable=true
                        supportMethodsArguments=true
                        params=count=countSql
                        autoRuntimeDialect=true
                    value>
                property>
            bean>
        array>
    property>
bean>

如果数据库是mysql，value标签内容为空

java代码使用pagehelper

//设置分页信息
		PageHelper.startPage(page, rows);
		//执行查询
		TbItemExample example = new TbItemExample();
		List list = itemMapper.selectByExample(example);
//		List list = itemMapper.selectItem();
		//创建一个返回值对象
		EasyUIDataGridResult result = new EasyUIDataGridResult();
		result.setRows(list);
		//取分页结果
		PageInfo pageInfo = new PageInfo<>(list);
		//取总记录数
		long total = pageInfo.getTotal();
		result.setTotal(total);
		return result;
